I've had these on my 2008 Explorer for about a year and about 12k miles. I've used them in extreme temperatures from over 100F down to -16F and in all types of weather without any issues. I've crossed Rockies twice and the Cascades numerous times with these. Current wear is reasonable. They arrived in a timely manner in good condition to the best of my recollection.Update: Feb2021, rotors are still holding up.Vehicle stops! that's a real plus :) Great price for complete kit for all four wheels especially with ceramic pads. My grandson installed with no problems. Everything was there - no missing parts! I was able to have brakes replaced all way round for what it would have cost me just to have old rotors turned at the shop.Product is well made,pads,,,no more brake dust,these rotors an pads were an excellent buy,an brakes are working excellent, some say rotors don't warp,not true,with these being slotted an drilled, except coolingGoodThey emailed me to make sure they had the correct info for what needed. Everything worked out great. Thanks guys.Exact fit and great quality. Fast shipping too. Would recommendPut on 2009 explorer..fit perfect! Excellent stopping power. Would recommend..great bang for the buckalways work great
